David Moyes' record over his first 50 games better than Sir Alex Ferguson, Arsene Wenger, Bill Shankly and Brian Clough

Ferguson took United from practically relegation to 2nd in his first season.
Moyes has taken us from 1st to 7th. And won no trophies.
Comparing these is as useless as comparing track times of racing drivers when they started their careers. What matters are the tools you're given, and what you achieve with them.
